Esophageal duplication cyst in a pediatric patient, case report.

Abstract

Background: Esophageal duplication cysts are of low incidence in pediatrics. Dysphagia is the main clinical manifestation. They can be associated with other malformations. The diagnosis must have imaging characteristics and must be confirmed with histopathological findings. Treatment in symptomatic cases is surgical to avoid complications. The objective of this case report is to sensitize the reader about a diagnosis that must be taken into account in the study of dysphagia, to make an early diagnosis and timely treatment avoiding complications. Case summary: 11-year-old patient with 2-year-old dysphagia, no other associated symptoms, no significant history, no other associated malformations. Within the study of dysphagia, an endoscopy of the upper digestive tract is performed and an injury is identified that extrinsically compresses the esophagus in its distal part, and can be corroborated with additional imaging studies. A complete resection was performed by videothoracoscopy and a diagnostic suspicion of esophageal duplication cyst was confirmed due to histopathological findings. It was possible to discharge without complications. Conclusions: Esophageal duplication cysts of the lower third of the esophagus are usually asymptomatic, however, sometimes they can cause nonspecific symptoms. They should be suspected within the differential diagnoses of patients with dysphagia, studied with imaging diagnoses and confirming with histopathological findings. Surgical resection is the treatment of choice and performed on time to avoid complications.
